Verbena plant named ‘Lan Rose’

ABSTRACT

A verbena cultivar particularly distinguished by rose colored flowers, vigorous growth and semi-trailing habit.

GENUS AND SPECIES

Verbena hybrida.

VARIETY DENOMINATION

‘Lan Rose’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of verbena, botanically known as Verbena hybrida, and hereinafter referred to by the cultivar name ‘Lan Rose’. The new cultivar is asexually reproduced from vegetative cuttings and tissue culture resulting from the cross of the seed/pod parent 98-684-2, an unnamed and unpatented red proprietary line and the pollen parent Temari Burgundy (PPAF), a commercial, unpatented line.

‘Lan Rose’ is a product of a planned breeding program intended to create new verbena cultivars with rose colored flowers, dark green foliage, vigorous growth and semi-trailing habit.

The new cultivar was created in 1999 in Gilroy, Calif. and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif. over a two year period. It has also been trialed at Gilroy, Calif.; Alberta, Canada, Litchfield, Mich. and Andijk, The Netherlands. The present invention has been found to retain its distinctive characteristics through successive propagations; and this novelty is firmly fixed.

DESCRIPTION OF PHOTOGRAPH

This new verbena plant is illustrated by the accompanying photograph which shows blooms, buds, and foliage of the plant in full color, the colors shown being as true as can be reasonably obtained by conventional photographic procedures.

The drawing shows overall plant habit and the mature inflorescence.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Lan Rose’. The data which defines these characteristics were collected from asexual reproductions carried out in Alberta Canada. The plant history was taken on 11 week old plants grown in 4 inch pots, blossomed under, natural light in a greenhouse and color readings were taken in the greenhouse in Alberta Canada. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.).

DISEASE AND INSECT RESISTANCE

Tolerant to mildew

COMPARISON WITH KNOWN CULTIVARS

When the instant plant is compared to ‘Temari Bright Pink’ (PPAF) the ‘Lan Rose’ leaf length is longer than ‘Temari Bright Pink’. ‘Lan Rose’ has a greater flower density than ‘Temari Bright Pink’. Additionally, the flower diameter ‘Lan Rose’ is a little less than that of ‘Temari Bright Pink’.

COMPARISON WITH PARENTAL CULTIVARS

When the instant plant is compared to the male parent ‘Temari Burgundy’ (PPAF) the ‘Lan Rose’ has a rose flower color and ‘Termari Burgundy’ has a burgundy flower color. ‘Lan Rose’ has more vegetative growth in the center of the plant than does ‘Termari Burgundy’. ‘Lan Rose’ is also earlier to flower than ‘Temari Burgundy’.

When ‘Lan Rose’ is compared to the female parent ‘98-684-2’, ‘Lan Rose’ has a rose flower color and 98-684-2 has a red flower. ‘Lan Rose’ has more trailing plant habit than 98-684-2 and is more mildew tolerant than ‘98-684-2’.
